Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Neutrinos, being the only fermions in the Standard Model of Particle Physics that do not
possess electromagnetic or color charges, have the unique opportunity to communicate with …

Searches for dark matter decaying into photons constrain its lifetime to be many orders of
magnitude larger than the age of the Universe. A corollary statement is that the abundance …

We present two complementary NuSTAR x-ray searches for keV-scale dark matter decaying
to monoenergetic photons in the Milky Way halo. In the first, we utilize the known intensity …

Sub-GeV dark matter particles can annihilate or decay producing e±pairs which upscatter
the low-energy photon fields in the Galaxy and generate an X-ray emission (via the Inverse …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

The main mechanism responsible for Axion-Like-Particle (ALP) production in the early
universe is the so-called misalignment mechanism. Three regimes have been investigated …

This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which
was focused on particle dark matter. One of the most important scientific goals of the next …

Neutron stars close to the Galactic center are expected to swim in a dense background of
dark matter. For models in which the dark matter has efficient interactions with neutrons, they …

Axion dark matter (DM) may efficiently convert to photons in the magnetospheres of neutron
stars (NSs), producing nearly monochromatic radio emission. This process is resonantly …
